Abstract
BackgroundSqueaking of ceramic-on-ceramic total hip arthroplasty is an unexpected complication which occurs in 1- 30% of patients. Revision surgery is required in 0.2% of the cases, when a ceramic fracture is suspected, or in case of severe malposition of the implants, subluxation, or impingement. Hip arthroscopy may be a useful diagnostic and therapeutic option in squeaking hips.Case presentationA patient presenting with a pain-free squeaking underwent hip arthroscopy to examine the sliding surfaces and the rim of the acetabulum, and to search for signs of impingement. Thorough lavage and debridement of hip synovitis and fibrous tissue was performed. The squeaking noise immediately disappeared after the surgery. The patient was allowed to fully weight bear as tolerated with 2 crutches for 2 weeks. Two years after the arthroscopy, the patient remained symptom-free.ConclusionsThe potential reasons for hip squeaking in our patient are discussed. Hip arthroscopy may prove useful as a diagnostic and therapeutic option for some patients presenting with a squeaking ceramic-on ceramic hip replacement.

Due to outstanding tribological properties, the ceramicon-ceramic (C–C) couple has been accepted as a reliable bearing surface in Total Hip Arthroplasty (THA), especially in young and active patients [1]
Summary
Squeaking of ceramic-on-ceramic total hip arthroplasty is an unexpected complication which occurs in 1- 30% of patients. With the increasing number of C–C prostheses implanted, two complications arose in patients treated with these bearings: fractures of the ceramic and squeaking [2]. A pelvis CT-scan was performed to measure cup and femoral stem orientation, and to detect a potential fracture of the ceramic.
